CLOTH-WINDING MAcHINE.

Application filed April 2, 1925. Serial No. 20,106.

To all whom it may concern:

Be it known that I, CHARLES Gr. RICHARD- soN, a citizen of the UnitedStates, and resident of Springfield, in the county of VVindsor and Stateof Vermont, have invented certain new and useful Improvements inClotl1-Winding Machines, of which the following is a specification.

This invention relates to the art of cloth winding, and particularly tothe winding of commercial lengths of cloth or fabric upon a core-pieceor winding board in order to package the cloth in the form of a flatbolt.

The cloth winding machines that are used for thus packaging the clothinto bolts are well known in the art and, therefore, need not beexplained in detail. Essentially they comprise two oppositely alignedboard-supporting heads or chucks which are rotated in unison to wind thecloth on the interposed winding board. As the cloth is kept undertension, during this winding operation, the core-board is subjected toconsiderable strain so that unless the board be of good quality andweight it is likely to buckle or break, in

either case producing imperfect packaging of the'cloth. It has beenproposed to use a metal stiffening plate as a permanent'part of thewinding machine to reinforce and support the core-board to preventsuchbuckling, but as the operator is-obliged to handle this stiffeningplate a great many times a day, the excessive weight of thestiffeningplates heretofore used has been a severe tax on the operator and hastended to slow up his work because of fatigue.

It is the object of the present invention to produce a stiffeningelement forcloth-winding machines of the type above referred to thatshall afford a full adequate reinforcement for the thinnest and mostflimsy coreboards used, while at the same time keeping the constructionso light as to greatly lighten the labors of the winding-machineoperator. A furtherobject of the invention is to afford full or completesupport for the core-board and for the cloth that is being wound aroundthe same.

To this end the invention comprises ahollow stiffening element ofplano-convex cross section presenting a fiat face affording support forthe core-board, and also affording complete support for the cloth beingwound around the core-board so as to insure perfect winding free fromwrinkling, while at the same time a very stiff and a very lightconstruction is obtained. To further increase the stiffness, withoutmaterially adding to the weight of the reinforcing or stiffening elementparticularly in cases where windingboards are used for wide bolts, Iinterpose spacing devices between the two members of thestiffeningelement to prevent any possibility of collapse or buckling.These and other features of the invention will be particularly describedin the following specification and will be defined in the claims heretoannexed.

In the accompanying drawings I have shown a simple, cheap and convenientem bodiment of the principles of this invention, in which: i

Figure 1 is a plan View of the stiffening element mounted in the opposedheads or chucks of a cloth-winding machine, the remainder of the machinebeing omitted. v

Figure 2 is a central longitudinal section of the stiffening elementheld in the opposed chucks.

' Figure 3 is a cross-sectional view of said stiffening board on anenlarged scale, showing the spacing devices or struts interiorlydisposed therein.

The stiffening element here is shown applied to twoopposed rotary chucksof wellknown construction. One of said chucks is usually hinged topermit the downward or lateral swinging of the wound bolt of cloth afterthe opposite end has been dis-engaged from its sup ortin chuck.

The hinge chuc in this case, comprises a'trunnion sleeve 10 secured to ashort stub shaft 9 by which it is rotated, and having on its oppositesides trunnions 10*, which form pivotal support for the forked clampinghead which is made in the form of a'yoke whose two outwardly extendingarms 12 arepivotally supported upon the trunnions 10 and whose bodyportion comprises transverse spaced jaws 12 between which is insertedthe adjacent end portion of the stiffening element or truss 20, and areheld in such inserted position by means of a cotter pin or equivalentdevice 13, which can be easily removed for inserting different sizes ofstiffening elements. A spacing member 14 is secured in the hollow endportion of the truss 20 and is perforated or bored to receive thepivotal connecting pin 13 and thus serves also as a bearing member so asto avoid bringing the whole longitudinal stress of the truss upon thethin edges of the truss plates through which it is preferably inserted.

The oppositechuck comprises a head 16 with oppositely projecting wingsor plates 16 and movable clamping jaws 17 which are clamped against theadj acent end portion of the inserted stiffening element by means ofclamping nuts 17*.

The stiffening elementitself, accordingto the form illustrated in thedrawings, comprises two sheet metal plates 21- and-22, one of which isflat presenting a plane surface affording full contact with thecore-board 25 to reinforce or support every portion of it, while theopposed sheet metal plate 21 is transversely bored to form an exteriorconvex surface which, nevertheless, affords; complate contact andsupport, for the cloth passing around wrinkling. The two plates 21' and22 are rigidly secured together along their sides or. longitudinal edgesin any suitable manner, as by rivetin weldingor the like, so

that there is proc need a very stiff, light,-

hollow truss affordingfullsupport both for the cloth and for thecore-board.

A spacing member 14 is inserted between the separated ends of thisreinforcing ele ment to occupy the medial portion of the end attached tothe hinged chuck. site end, that is the end that is releasedfrom thechuck to permit removal of the wound bolt,.the plate 21 is flattened tolie in parallelism with the adjacent end portion of the plate 22 soas'to reduce the thickness of the stiffening element atthe end fromwliichthe cloth bolt :is removed, and also afford a proper shape forfirm clamping engagement betweenthe jaws 16 and 17 of the releasingchuck, c

To further stiffen the structure I introduce along the medial line aseries of short spacing devices or studs 23., particularly where thestiffening element is made of extra length for wide bolts.

In practice,the core-board or bolt-board is placed against the fiat faceof the stiffen; ing element 20- so as to liebetween the; projectingledges formed at each end by the jaw 12 and the jaws 17, and is held inplace by simply wrapping the initial end of the cloth around theassembled core-board and stiffening element for one or'two turns, afterwhich the machine is started in operation to complete the winding of thebolt. To remove the cloth-board'the clamping nuts 17? are releasedsufficiently to allow the stiffening element to be swung edgewise outfrom between the clampingjaws 16 and 17, which movement is permitted bymeans of the.

pivotal connection afforded by means of the pivot or fulcral pin 13,carried by the hinged chuck and passing through aligned aperthat face,thereby avoiding At the oppo-.

holding jaws 12 should snugly embrace the fulcral end of the stiffeningmember but not with sufficient grip orfriction to prevent the swingingof the. stiffening element to openposition to permit the removal of thecloth-bolt. I

It will, therefore, be seen that this truss element not only provides afull supporting surface in complete contact with the coreboard on oneside and the cloth 'on the other side when a core-board is used, but itis also capable of forming the whole support or re-' enforcement for thecloth being Wound when it is desired to package the cloth Without anyinterior core-board.

What I claim is: p 7

In a cloth-winding machine, the combination with rotatablesupportingchucks, of a hollow rigid trussmember of planoconvex cross-sectionhaving one end pivot,- ally connected with one of. said chucks forrotative support and having. its opposite end detachably secured'to theother chuck, thereby providing a reinforcement aff'ording on its planeside complete support for the subtending area of one side of core boardand on its convex side affording complete supporting contact with thesubtending area of theicloth,

2. 'A reinforcing element for a cloth wind-ing machine embracing in itsconstruction twov sheet metal plates firmly secured togethen along theirside edges, one of said plates being transversely bowed to present anexterior convex cloth-supporting surface, the other plate being flat topresent aplane surface to a core-board placed against it and afford fullsupport therefor, substan tially as-Idescribed.

3. A reinforcing element for a clothwi'nding;machineembraeing two sheetmetal plates'secured rigidly together at their side 1 edges, one of saidplates being transversely bowed, the'other plate being flat, a spacingmember interposed between the plates at one end, said plates beingapertured at that end for the reception of a fulcral connecting pin,substantially as described.
